The study of plant life is called "botany." This branch of biology focuses on the scientific study of plants, including their structure, function, growth, reproduction, and ecology. Botany encompasses a wide range of topics, from the microscopic examination of plant cells to the study of entire ecosystems. Botanists explore the various roles plants play in the environment, such as producing oxygen, providing food, and forming habitats for other organisms. Additionally, botany contributes to agriculture, horticulture, and conservation efforts, ensuring sustainable practices that benefit both humans and the planet. Plant studies are crucial for understanding biodiversity and ecological health.
